Masterbatches is
basic in adding colours or pigments to plastic, and which make the
plastic material, usable for different industries. With advancement in
technology, masterbatches are available today with addition of
anti-oxidants in them, which make the plastic healthy and good for use
for the container of edibles. Before learning the uses of masterbatches
with anti-oxidants, let us understand what they are.
Antioxidants masterbatches are they type of additive masterbatches which has minimal concentrations of it which helps retarding polymer oxidation and removing the possible de-gradative effects.
Polymers are exposed to the impact of external sources during the process of polymerization. In addition, this can lead to degradation which further consequence to discoloration, change in viscosity, loss of physical properties, loss of clarity and surface crazing.

Uses of Anti-Oxidants in Masterbatches
- Antioxidants in masterbatches are used to protect polymers present from oxidative degradation during processing and, which are commonly added by resin producers during the process of manufacturing.
- These antioxidants are divided into broad categories of primary, secondary and primary/secondary combination.
- Primary Antioxidants: Those which are used to add finishing to the product and they ensure stability .
- Secondary Antioxidants: Those which are used to protect polymers from oxidation and used for stability.
- Primary/Secondary Combinations: The combination is used to protect polymers during both stages of processing and its service life.
There are different types of anti-oxidants which are used and serve different purposes. One of the many kinds include phenolic primary anti-oxidant which ensure stability and long term heat stability to polymers such as polypropylene, polyethylene, polyamide, polyester, polystyrene, polyurethane and polyvinyl chloride.
These type of polymer additives masterbatches are used in cable industries, reprocessing, blow moulding, pipes, filled compounds, BOPP films, tapes and more.
Anti-oxidants are imperative in masterbatches which ensure the stability of pigments in the product.
